Add support for acroforms

[Heston1]

A feature implementing AcroForms since its supported in the underlying library PDFKit although there is no direct support for checkboxes and radio buttons because it was removed in PDFKit but I've decided to implement it here.

Files src/pdf-kit-extensions/PDFEmbeddedFont.js and src/pdf-kit-extensions/StandardFonts.js in pdfmake are they needed for what?

Checkboxes and radios support in src/pdf-kit-extensions/ExtendedAcroFormMixin.js will be better first implemented in pdfkit.

PDFEmbeddedFont.js is a workaround to embed the entire font, pdfkit doesn't have an option to do this that's why there is this issue foliojs/pdfkit#1096, in adobe acrobat it defaults to another OpenType font if the glyph is not included I think to something like myriadpro, whereas with chrome you only see the glyphs included in that subset font only, atm im using this for something but I will try to get checkboxes and radio forms, and this issue in pdfkit and get back to this when its in.

foliojs/pdfkit#1096 require fix in pdfkit (not in pdfmake).

@Heston1 Great work, a layout for forms is exactly what need ❤. I will try to use it as fast as possible.
Maybe you should also include your features in the features list in the readme.md?

@reinerBa can you please resolve conflicts?

@liborm85 @bpampuch do you approve this feature to be added to PDFMake?

[reinerBa]

@techquestions Sorry but i haven't written any Code in here and i see no conflicts. I did just build the fork of Heston1 for my purpose.

Utter heros in here.

I'm seriously considering using an unmerged PR... based on an alpha not-for-production version... of a lightly-maintained project... in production.

Is there any progress on this? Will this be merged at some point or not at all?
